How to Podcast for Free

Getting started with podcasting can be a laborious process, because it costs time to produce and money to host a podcast.

At Auphonic, we are constantly trying to make this process simpler and cheaper, not just through our own free automatic audio post production web service, but also by offering tight integration with various third-party services.

In this article, we will show you how to set up a podcast in a few minutes for free. The final solution includes a blog with a feed from which your listener's can directly access your audio and video files, all hosted on ...


Amazon S3 and Archive.org Now Supported by Auphonic

In case you have not noticed already, Auphonic now supports Amazon S3 and Archive.org as external services. Archive.org, also known as the 'Internet Archive', is a great service for publicly hosting audio and video files for free. Amazon S3, on the other hand, provides both free and affordable services for public or private file storage, featuring better download speeds and high durability. S3 also interfaces with Glacier, Amazon's cheap solution for long-term archiving and backups of data that does not require rapid access.

Similarly to our support for Dropbox, YouTube, Soundcloud, Libsyn, and FTP/SFTP, you can ...

Loudness Targets for Mobile Audio, Podcasts, Radio and TV

Have you ever wondered how loud your audio productions should be? So have we, because it's a quite tricky question to answer!

On the one hand, you want to make sure your productions are loud enough. For example, they should still appear at a reasonable level in noisy environments (car, airplane, etc.), and their loudness should be comparable to that of other programs, no matter whether those are produced by yourself or by others.

On the other hand, you certainly don't want to compromise sound quality for sheer loudness. We have discussed in Audio loudness measurement and normalization ...


Libsyn Podcast Hosting now supported by Auphonic (+ free promo code)

Podcast hosting is difficult: you have to create an RSS feed, a webpage and you must be able to serve audio files to a huge number of clients on your release date.
That's why we integrated the popular podcast hoster Libsyn (Liberated Syndication) as an external service in Auphonic. It's a great tool for file hosting and automatic RSS feed generation after processing and encoding your productions with Auphonic – you can even record your podcast with the Auphonic App and publish it with Libsyn immediately! :)

About Libsyn

Liberated Syndication was one of the first podcast hosting services when ...

Automated Batch Processing of Audio and Video File Collections

Do you want to process huge amounts of audio or video files in one single step?

It allows you to start multiple productions with an existing Preset and can be used for file-based, automated batch processing of audio file collections.

Step 1: Select Preset and Files

First you have to select multiple input files and one preset. A preset stores common metadata, output file formats, outgoing file transfers and algorithm settings for your productions. All input files will be processed with settings from the preset.

Opus, the revolutionary open audio codec for podcasts and internet audio

We are very happy that Opus, an exciting new open audio codec, is now officially standardized by the Internet Engineering Task Force (IETF). Opus is particularly interesting for podcasts, radio books and internet audio in general due to its suitability for both, music and speech, and its outstanding sound quality at also very low bitrates.
In this article, we will listen to some examples of the Opus codec in action and have a closer look at the codec and how audio producers can benefit from it.

Automatic Content Deployment: Video, YouTube and SoundCloud Integration

This summer, we proudly released three important new features: video support, YouTube export for audio/video and the SoundCloud integration!
These features make it possible to use Auphonic for the automatic deployment of podcasts, screencasts, recordings, etc. to multiple platforms - see External Services.

The combination of SoundCloud and Auphonic provides a complete package for podcast post production, hosting, RSS feed generation and more.
Furthermore, the YouTube export function allows you to increase your audience through YouTube's content discovery mechanism, including listeners that you could not reach through a podcast RSS feed.


All file metadata, images and chapter marks are ...



Audio loudness measurement and normalization with EBU R128 (Calm Act, ATSC A/85)

Have you ever wondered why commercials sound louder than your favorite TV shows? Or why you have to adjust the playback volume on your television when switching between channels? The answer is that until recently, there was no standard way to measure the perceived loudness of sound recordings. Instead, audio productions were (and still are) normalized to peak levels, which do in no way determine how loud a signal is.

In this article we will discuss the EBU recommendation R128, a new and open standard for balancing audio programs according to their actually perceived loudness.

This recommendation marks one of ...
